Sneak Peak Clinical, wrong result?

I took the Sneak peek clinical at 8 weeks 3days. I got boy results. I have a 5 month old boy. I have been reading that TONS of people get false boy results, and that some people believe sneak peek is a scam. I am scheduling a 3D ultrasound around 15 weeks to confirm. Has anyone done the clinical version of sneak peek and had false boy results?
